Bring a large pot of salted water to a boil. Cook the pasta for 7-9 minutes or until al dente. Reserve 1 cup of pasta water before draining. Set aside the cooked pasta.
In the same pot, combine peanut butter, soy sauce, garlic, sriracha, sesame oil, rice vinegar, ginger, honey, and ½ cup pasta water. Whisk until well combined.
Heat the sauce over low heat until thickened.
Remove from heat and toss the pasta with the sauce. If too thick, add 1 more tablespoon of pasta water and stir until smooth.
Top with peanuts, cilantro, green onions, sesame seeds, and a squeeze of lime juice.
Serve immediately.
